ASSA 6000 HIGH SECURITY CYLINDER

The ASSA 6000 cylinder is a significant development in lock technology. Most conventional cylinders can be easily defeated by skilled manipulation or simple brute force. Even many so call "high security" cylinders suffer from a critical lack of key control-duplicate keys are easily obtained by unauthorized persons because there is no method to control key blanks. ASSA 6000 meets both requirements of high security cylinders uncompromising physical security and patented key control

PICK RESISTANT

The ASSA 6000 cylinder resists picking by any commonly known method. Two independent locking mechanisms ensure optimum pick resistance. Inactive "dummy" grooves in the side pins catch the side bar when improperly positioned. When rotational force is applied in a conventional picking attempt, the mushroom-shaped drivers are caught by counter milling in the cylinder plug.

DRILL RESISTANCE

Drills are sometimes used to destroy brass cylinders and open locks. Vital points in the ASSA 6000 are protected by case-hardened, drill resistant inserts. All pins are nickel silver or stainless steel.

KEYS AND KEY CONTROL

The ASSA high security key is a precision crafted security tool. Two sets of bittings (or key cuts) operate the double locking mechanisms. Detail and quality are clearly evident. Even the back of the key is rounded for smooth operation and minimal wear. The enlarged key bow accommodates use by manually impaired people, and the unusual strength of the key virtually eliminates breakage.

The ingenious design of the ASSA 6000 key and cylinder has recently earned patents in the United States and may other countries. Patents are crucial in the effort to eliminate unauthorized duplicate keys and maintain rigorous key control. Any infringement of the ASSA patent rights will be forcefully prosecuted in the courts.
